Abstract: Objectives: To systematically review interdisciplinary inversion approaches integrating geodetic observations with geophysical modeling (geodetic-geophysical joint inversion), enhance the theoretical understanding of multimodal data fusion in Earth system science, foster geodetic innovations for national strategic needs in natural hazard mitigation and geodynamic monitoring, and highlight ways to strengthen the synergy between geodetic precision and geophysical modeling in next-generation Earth observation systems. Methods: Starting with the conceptual framework of geodetic-geophysical joint inversion, elaborating its fundamental principles and research scope from three main dimensions. Conducting a comprehensive historical analysis of the development of this multidisciplinary paradigm in global and domestic research. Focusing on three key applications: seismic source characterization through waveform inversion, kinematic rupture process modeling, and crustal deformation velocity field reconstruction. Results: A review of the evolutionary trajectory of the geodetic-geophysical joint inversion paradigm is presented. Insights into the three key applications are provided. Current methodological challenges are identified. Conclusions: Strategies for promoting integrated inversion techniques are proposed. The importance of strengthening the synergy between geodetic precision and geophysical modeling in future Earth observation systems is emphasized. -
